STATION-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 625,553, dated May 23, 1899.

Application filed August 9, 1898.

T0 aZZ whom it may concern.-

Be it known that I, HERMAN A. HAOKELING, a citizen of the United States, residing at New York, in the borough of Manhattan and State of New York, have invented certain new and useful Improvements in Station-Indicators, of which the following is a specification.

This invention relates mainly to stationindicators of that class which are attached to passenger-cars and in which as the car passes the station or street the indicating mechanism is operated so as to indicate the next station or street to the passengers.

The object of the invention is to provide an improved form of actuating mechanism for the indicator, so that the indicating mechanism maybe used when the cars are moved in either direction.

Further objects are to generally simplify and render efficient the street indicating mechanism of this class.

The invention consists of certain features of construction and combinations of parts to be hereinafter described and then particularly claimed.

In the accompanying drawings, Figure 1 is a vertical longitudinal section of a portion of a car with my improvements applied thereto. Fig. 2 is a face view of the indicating mechanism. Fig. 3 is a vertical longitudinal section of the same on line 3 3, Fig. 4; and Fig. 4 is a vertical section on line 44, Fig. 3. Fig. 5 is an enlarged detail View, partly in section, of the actuating mechanism for the indicator, showing the same in one position; and Fig. 6 is an elevation of the same, showing the parts in another position just after the indicator has been shifted. Fig. 5 is a side elevation of the notched disk shown in connect-ion with the detents. Fig. 5 is a detail in vertical section through the upper end of the reciprocating rod, showing how the check-pawl is mounted thereon. Fig. 7 is a detail elevation of the same parts, showing the double or U-shaped pawl shifted for the return trip of the car. Figs. 8 and 9 are sectional detail views of the mechanism arranged under the bottom of the car. Fig. 10 is a transverse section through one of the rails, showing the raised cam portion. Fig. 11 is a longitudinal sectional view of a portion of a car, showing a modified form of the invention. Fig. 12 is a vertical trans- $erial No. 688,145- (No model.)

verse section through the casing containing the indicating mechanism and showing the modified form of actuating mechanism. Figs. 13, l4, and 15 are views of the modified form of actuating mechanism in different positions, corresponding with the positions shown in Figs. 5, 6, and 7, respectively. Figs. 16 and 17 are enlarged detail views, respectively, of the actuating-pawl of the modified form and a cross-section on the line 17 17, Fig. 15.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A indicates a car, whether it be an electric, horse, or other car or coach, which is provided with my improvements for indicating the streets or stations. In the well-known manner the track is provided at the points corresponding with the stations or streets with raised cam portions B, which act on the push-pieces B, that are guided in sleeves (J, suitably fastened or bolted to the bottom of the car-body. The push-piece B is held in normallydowered position by means of a spring I), coiled within the guide-sleeve C, while the other end of the push-piece B is pivotally connected with the rock-arm d at the inner end of the rock-shaft D, which is journaled in suitable boxes D, fastened to the bottom of the car-body. The outer end of the said rock-shaft is also provided with a rock-arm d, to which is connected the pull-chain e for the indicating mechanism that is contained in the car-body. There is nothing new in this particular mechanism arranged on the body of the car, and my invention resides in the actuating mechanism arranged in the car.

In Figs. 2 to 7 my improvements are clearly illustrated. Fixed in one end of the interior of the car A is a case or cabinet E, and in a suitable bearing-frame E, arranged in the said case, is journaled a pair of drums F F, and upon these drums is wound the indicating band or apron I, which is guided over suitable guide-rods I, fixed to the frame E. The indicating band or apron I is provided either on one or on both sides at proper intervals with the names of stations or streets in the well-known manner, so that the indicator will show the names of the stations or streets whether the cars move in one or another direction. In case the car returns by the same route it had taken previously the indicator will show the stations or streets on the returning route in the reverse succession, as the band is simply unwound from the drum onto which it is wound and again wound up during the next trip. In this case it is evident only one side of the band needs to bear the names of stations or streets. In those cases, however, where the cars return-by a route different from the one taken before the band or apron is provided with the names of the stations or streets on both sides, one side being necessary for each route. To effectuate in this event the correct indication of stations or streets, the front or face plate of the case E is provided with upper and lower observation slots or openings 6 6 respectively, and corresponding with the two drums F F, hearing the band or apron, which shows a difierent side on each drum. According to the route by which the car may be moving, the one or the other slot is closed by means of any suitable arrangement, as by doors D D hinged to the front plate of the case, as shown in Figs. 2 and 3. That only one observationopen'ing is necessary when the car returns by the same route it had taken previously is evident. The chain e, previously referred to, passes through the bottom of the car and is guided at its upper end around a suitable pulley e and through an opening in the case E, in which the said upper end of the chain is attached to the lower endv of a reciprocatory and weighed rod G, that is guided in a suitable guide 9', fixed to the inner wall of the case. To the upper end of the rod G is pivoted at h an oscillatory and U-shaped or double actuating-pawl H, this pawl being adapted to be shifted to one side or the other and held in shifted position by means of a suitable spring. J J are bent plate-springs which diverge or flare outwardly from a pivot j, which is journaled in the car, so that it can be rocked by a suitable knob or button J (See Fig. 4.) The free ends of the springs J J span the double pawl, so that each can engage with the corresponding end of said pawl. Only one spring at a time, however, can bear against the double pawl. The recessed ends h of the double or U-shaped pawl H are adapted to take against laterally-projecting pins 70, that are arranged in circular series on one side of a rotary disk K, that is fixed on the extended end of the shaft F of the lower drum F. By the engagement of the pawl H with the lateral pins k on the disk K the latter is rotated, and through the medium of a gear-wheel L, which'is fixed on the shaft F and that intermeshes with another gear-wheel L, fixed on the shaft of the drum F, both of said drums are simultaneously turned in opposite directions. The disk K is provided at suitable intervals on opposite sides of its periphery, corresponding with the distance apart of the pins-7c, with notches or recesses k respectively, into which the or tilted from side to side. the check-pawl is limited by a pin h", passing points or beveled noses m ofdetents M M are adapted to take. The notches 70 at one side of the periphery of the disk K are beveled in opposite direction from the notches 70 at the opposite side, while the noses m, which take in said notches, are beveled correspondingly thereto. The detents M M diverge from pivot j, on which the springs J J are fixed. Hung on the same pivot h with the double pawl H is a check-pawl S, which is made quite broad at its pivoted end and tapering to a point at its free end. It is mounted so as to extend in an upward direction between the ends of the double pawl and so thatit can be shifted The movement of through the rod G above the pivot h and through a curved slot in the said check-pawl. (See dotted lines, Figs. 5 and 7, and detail view, Fig. 5 The operation of this form of the invention is as follows: As the car passes astation or street the push-piece B is raised by the cam B on the track-rail, the shaft D rocked, and a downward pull exerted on the Y pull-chain e, which thereby raises the reciprocating rod G. It is assumed that the U- shaped or double pawl H has been swung over into the position shown in Fig. 5 by tu rning the knob J on pivot j in the direction indicated by the arrow, so that the spring J bears upon the corresponding end of the double pawl and the detent M engages by its beveled nose in one of the notches 7c of rotary disk. double pawl will take against the pins on that side of the rotary disk K corresponding thereto. When the rod G is being raised, the said end of the double pawl which is in engagement with one of the pins 76 will impart a partial rotation to the disk K in the direction of the arrow, the distance moved corresponding to that between any two adjacent pins or notches 7t and the pawl overcoming the detaining action of the detent M, which prevents the reverse turning of the said disk when not positively turned. The check-pawl pawl S moves up against the lower pin 7.; and prevents the overrotation of the disk. The partial rotation, as described, of the disk K imparts a partial rotation to the drums F F and shifts the indicating-band I so that the name of the proper street or station is shown through the opening 8 the other opening being closed up. The position of the rod G and the pawl H when raised is shown in Fig. 6. Referring to Fig. 7, it will be seen that the U-shaped pawl H has been oscillated by the knob-controlled spring J so that the other end of the pawl will engage the pin is at the opposite side of the disk K and so that the other detent M will engagethe other series of notches 1.5 The pawl is set into this position just before the return trip of the car, sothat whenever the station or street is being passed the disk will be turned in the direction of the arrow and the indicating-band thereby moved in the opposite direction. Be-

In this position the said end of the.

fore making the return trip (only, however, when the car takes another route) the opening 6 is uncovered and the opening 6 of the case E covered, so that the stations or streets on the opposite side of the indicating band or apron will be disclosed. By thus constructing the actuating mechanism it will be observed that the same can be quickly adj nsted so that the stations or streets, whether the car run in one or the other direction, may be accurately indicated.

In the modified form of the invention shown in Figs. 11 to 17, inclusive, the rod G has the push-piece I3 at its lower end, the intermediate connections before referred to being dispensed with. The rod G is moved normally downward by means of spring g While the upper end of the rod G is provided with a transversely-slotted head 9 in which engages a pin 9'' on the double push-pawl device N. The double push-pawl device N is composed of a cross-bar n, from which the pin 9 extends, and two upright arms n Pawls O 0, respectively, are pivoted to the upper ends of the arms a and are directed inwardly by means of springs 17, which are fixed at 19' to the arms n of the push-pawl device and which act by their free ends upon pins 19 on said pawls O O. The pawls O O are prevented from moving farther in than to a position at right angles to the arms 11 by means of stoplugs 0 which engage the upper ends of said arms. By this construction the pawls O O are permitted to perform active service when moving up in contact with the pins k on the rotary disk K; but when the rod G is lowered by its spring 9 the pawls will slip by and pass the said pins. In this form of the invention the disk K is detained by a single detent Q, which engages theV- shaped notches 10 Fixed to the pin 9 of the pawl device N is a knob or button H which extends through the case E. This button is moved to one side or the other, so as to shift the push-pawlN to one side or other, according to the direction in which the car may be moving; but otherwise the action of the same is substantially like the main form of the invention, inasmuch as the pawl 0 will act when going in one direction and the pawl 0 when going in the other direction.

It is evident that my mechanism for indicating stations or streets may also be used to locate public buildings or private business places, &c., by substituting for the band or apron bearing the names of stations or streets a band bearing the names of such localities. (See A B O at upper part of. Fig. 1.)

Having thus described my invention, I
